feat(ops): answer "what datastore does this app actually use?" - #436
Merged
Conversation
Asked whether anything still used the self-hosted Supabase stack, I grepped DATABASE_URL across every app env. Every hit pointed at localhost:5432, so the answer looked like "nothing" — and stopping the stack was one command from taking orangecat and botsmann down, with 114 auth users, 114 profiles and 927 messages behind it, written to as recently as the previous evening. A Supabase app never sets DATABASE_URL. It talks HTTPS to PostgREST/Kong via SUPABASE_URL. Absence of a Postgres connection string is not absence of a dependency; it is the signature of a different one. This reads BOTH bindings per app and reports whether a Postgres target actually contains tables, so an empty database cannot masquerade as the live one. What it found on first run: orangecat, botsmann -> self-hosted Supabase (supabase.orangecat.ch) printcraft -> HOSTED supabase.co, never migrated off the cloud 12 apps -> native postgres native db orangecat -> exists with ZERO tables, referenced by nothing Read-only. The question "is X safe to stop?" now has a factual answer instead of a confident wrong one.

Grepping one binding and concluding "unused" reads absence as an answer.This reads both bindings per app, and reports whether a Postgres target actually holds tables, so an empty database cannot masquerade as the live one.
